ASTM D3703-99(2004)

The magnitude of the peroxide number is an indication of the quantity of oxidizing constituents present. Deterioration of turbine fuel results in the formation of peroxides and other oxygen-carrying compounds. The peroxide number measures those compounds that will oxidize potassium iodide.

The determination of the peroxide number of aviation turbine fuels is significant because of the adverse effect of peroxides upon certain elastomers in the fuel systems.

1.1 This test method covers the determination of the peroxide content of aviation turbine fuels.

1.2 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see 6.3, 6.5, 6.6, 8.2 and Annex A1.
